FIG. 1 depicts a ring assembly being worn on a finger. A customizable ring assembly 100 includes a shank 105 worn on a finger. The shank 105 may be formed in a hollow-cylindrical shape. In some exemplary embodiments, the shank 105 may be adjustable in diameter. In other exemplary embodiments, the shank 105 may be fixed in diametric size. The shank 105 includes a mounting portion 110 for releasably receiving the interchangeable module 115. The mounting portion 110 of the shank 105 has a lesser thickness than the remaining portion of the shank 105, such that when the module 115 is coupled to the shank 105 the outer surface of the module 115 is flush with the outer surface of the shank 105. The shank 105, mounting portion 110, and module 115 may be rigid in structure. The module 115 may be decorative, such as by being a certain color or colors, having a specific pattern, logo, or emblem, commercial slogans, or having an attached gem stone, for example. In some examples, the module 115 may be representative of a country flag or symbolic colors. In other examples, the module 115 may include a representation of a sporting device, such as a soccer ball, baseball, or hockey stick. In some examples, the module 115 may include a three-dimensional model, such as Olympic rings, for example.

FIGS. 2A-6 depict detailed views of exemplary components of the ring assembly. As shown in FIGS. 2A-2B, the interchangeable module 115 is removably coupled to the cylindrical annulus of the shank 105 of the customizable ring assembly 100 along about 180 degrees of the shank 105 circumference. In some examples, the interchangeable module 115 may be removably coupled to the cylindrical annulus of the shank 105 along about 90 degrees of the shank 105 circumference. In other examples, the interchangeable module 115 may be removably coupled to the cylindrical annulus of the shank 105 between about 90 degrees and about 180 degrees of the shank 105 circumference.

The shank 105 and the interchangeable module 115 include alignment features 120, 125 to prevent unwanted movement of the interchangeable module 115 relative the shank 105. In the depicted example, the shank 105 includes an alignment notch 120 extending along opposing longitudinal peripheral edges of the mounting portion 110. The interchangeable module 115 includes an alignment ridge 125 extending along opposing longitudinal peripheral edges of the interchangeable module 115. The alignment ridge 125 of the module 115 aligns with the alignment notch 120 of the mounting portion 110 to prevent the module 115 from moving back and forth relative the shank 105. The module 115 and the shank 105 also include opposing blunt ends to make contact when the module 115 is coupled to the shank 105 to prevent the module 115 from rotating relative the shank 105. The blunt ends may include alignment features, such as for example a recess and tab structure.
